RADIATOR.

SPECIFICATION forming part of Letters Patent no. 551 ,489, datedDecember 17, 1895. Application filed July 8, 1895. Serial No- 555,235.(No odel.)

To all whom it may concern.-

Be it known that I, J OSIAH B. FOX, a citizen of the United States,residing at Slatington, in the county of Lehigh and State ofPennsylvania, have invented certain new and useful Improvements inRadiators; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in radiators, the same beingdesigned for the purpose of utilizing the waste products ofcombustiomwhich ordinarily pass out into the air from the chimney. Inhouses of two or more stories a fire built in a room on the first storycan be made to heat those in the stories above by passing the wasteproducts of combustion through the radiator and thence out through thechimney.

The invention consists of a drum divided off into three or morecompartments, through which the waste gases pass, a series of lateraldefiecting-pipes extending across said drum, arranged in pairs, themembers of each pair being in parallel vertical planes, but set at aninclination with relation to the bottom of the drum for the purpose ofdrawing cold air in at the lower ends of said pipes and dischargingheated air through the upper ends thereof. This drum may have asurrounding casing, cylindrical in form, for hiding the ends of thedeflecting pipes or tubes and have the lower ends of said pipes projectthrough. The invention is clearly illustrated in the accompanyingdrawings, in which Figure 1 represents a side elevation of my device.Fig. 2 is a cross-section through the same. Fig. 3 is a vertical sectiontaken on the line :0 cc of Fig. iis a crosssection taken on the line y yof-Fig. 1.

Like reference-numerals indicate like parts in the various views.

The drum 1 of the radiator is made preferably cylindrical in form, ofsheet metal, has an inlet-opening 2 at the bottom, through which theproducts of combustion from any suit-able source are led into the drum,and an exhaust-opening at the top, through which the waste gases are ledback to the chimney and discharged into the air. The drum 1 has a seriesof hot air deflectors 4: 4 extending through the same, the saiddeflectors being arranged in pairs, the members of which are in parallelvertical planes, but are set at an angle to the bottom of the drum 1.The lower ends of these deflecting-pipes project through the outside ofthe drum 1 in order to take in cool air and also to prevent the airdischarged from the upper end of the lower pipes 4 from being admittedto the lower ends of the upper pipes. I also provide a series ofvertical pipes 5 in the drum 1, which increase the radiatingsurface andtend to further utilize the heat contained in the waste gases passingthrough the drum. These have inlet-openings in the bottom andoutlet-openings in the top of said drum. A series of vertical partitions(3 are arranged inthe drum 1, dividing the same off into compartments,as shown. The drawings illustrate three compartments, and this number Iprefer to use. 7 These partitions are so arranged that the products ofcombustion entering through the inlet-opening 2 pass up through one ofthe compartments made thereby, down through the adjacent compartment,and up through the remaining one, passing out through thedischarge-opening 3 in the upper end of the drum. By this constructionthe waste gases are forced to pass through the drum three times, so thatall the heat possible contained therein may be utilized for h eating theair in the deflecting-pipes i. 011 the outside of the drum 1 I may, if Iprefer, place a protecting-casing 7 which is cylindrical in form, openat top and bottom and supported upon lugs or projections extendingoutwardly from the drum 1. lVhen this protecting-casing is used thelower ends of the deflectingpipes 4 may be passed through an opening insaid casing.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a device of the character setforth, the combination of a cylindrical drum having an inlet opening atthe bottom for admitting the products of combustiomand an outlet openingat the top for discharging the same, and a series of deflecting pipespassing transversely through said drum, arranged in pairs, the membersof each pair being in. parallel horizontal planes and set at an angle tothe base of said. drum and oppositely inclined to
